Sažetak

In a traditional environment, hydropower plant owners seek for minimum
cost while in today deregulated environment goal function is profit maximization.
Besides electricity only market, power producers can offer their services also in
ancillary services markets. By doing so, it is possible to increase expected profit.
This paper focuses on simultaneous hydropower plant biding in electricity and
ancillary services markets, and purpose is to examine and verify effects of the
proposed method on expected profit of hydropower plan owner. A mathematical
model based on mixed integer programming approach is used. Head effect is also
take into account with price-wise linear performance curves. Prices from real
electricity markets and ancillary markets are used, and real hydropower system
Lokve-Bayer in Croatia, with focus on hydropower plant Vinodol, is modelled.
Obtained results show that there is a notable improvement in expected profit of
hydropower plant if presented market bidding approach is used. It is also shown
that hydropower plant Vinodol is capable for simultaneous bidding in different
power markets.
